Should I attend a Baby Shower?

A long-standing friend of mine is expecting a Baby and has invited me to the Baby Shower. I know many of the other women that will be there, but am not totally sure that I should attend, as I'm a crossdressing male. Yes, I know I wouldn't have been invited if I wasn't going to be welcome, but what of the guests that don't know me? How would you feel if a CD rocked up at one of your friends Baby Shower?

I'm totally happy to meet new people, but am a bit worried that maybe this isn't the right environment.
